This observation of his is what drove him to start studying further and become a psychology student, thus studying the matter in depth.
He went ahead to study the matter further by conducting longitudinal studies as to who would be able to stick around more and be successful in their respective field.
His final conclusion was that people who had the "grit" to stick around and have the consistency to pursue things were the one's who were more successful and were able to achieve their dreams.
